finally got behind the wheel to bleed brakes, hit a snag with the rears Options

[Type 47]

It was super cool to get behind the wheel, even though I'm sitting on a 6x6 piece of wood.

so bleeding the master and front went OK; we got nothing on the backs.

I suspect the brake pressure regulator needs to be wacked or something.

Please advise before I do something stupid.

Some videos show a different BPR, this is a 75'

You might have better luck using a pressure bleeder to move fluid through system. You either have blockage, a leak, or not enough fluid in the system.
Did you install a new MC? If you haven't removed the belly pan/mc cover yet (or put it back after installing the MC), remove it and check there for a leak.

Have you checked to see if the line is blocked going into or out of the regulator yet?

When bleeding brakes on a 914, I've always read to start with the right rear (furthest away from the MC).

We didn't put a new MC. The car was completely disassembled, painted, and now being reassembled.

there is fluid coming out of the feed line. we did start with the rears but when no fluid went to the fronts. they bled fine.
